IMPROVEMENT IN ROLLS FCR READUCING OLD RAILS.

Specification forming part of Letters Patent No. 154,789, datedSeptember 8, 1874; application rled July 3, 1874.

To all whom it may concern Beit known that we, JOHN P. EDWARDS, ofCleveland, Cuyahoga county and State of Ohio, and-AMRLER J. ROGERS, ofJackson, Jackson. county, State of Michigan, have invented anImprovementin Rolls for Reducing Steel Rails, of which the following isa Specification This invention relates to certain improvements in rollsfor reducing old steel rails or fagots into bars; and consists of a pairof rolls having peculiar grooves, whereby the rail is drawn throughbetween them in a diagonal line frorntheir axis, in such a manner thatthe rail is thickened up or upset between the edges of the anges, andalso between the anges through the body Iof the 1ai1withv out lappingthe metal. This process is necessary in the operation of reducingBessemer steel, because of its non-Weldin g quality.

To fully understand this invention we proceed to describe the samewiththe aid of the accompanying drawing, in which the gure is a Sideelevation of a pair of rolls having the aforesaid grooves.

A B represent tWo rolls mounted in suitable housings for working `inconcert. The grooves, it Will be observed, in these rolls, instead ofbeing at right angles with the circumferenee, are V-shaped, and therolling surfaces also are at an angle of twenty degrees from thecircumference line.

By making the grooves in this manner the entrance thereto isfunnel-shaped, so that the grooves are a little smaller than the railwhich enters them, and is therefore griped and drawn in, and, instead ofbeing lattened in one drection', is contracted in all points centrally,and fulling it up through the body of the rail. Let it be noticed thatthe first groove l is narrower across the flanges, and is shorterdrawingout into square or flat bars old steel rails.

Having described our invention, We claim- The rolls A B, having thegrooves l 2 3 4 5 6, as shown and described, substantially as and forthe purpose set fort JOHN P. EDWARDS.

YAMBLER J. ROGERS.
